Filter by:The goal of this observational study is to explore the different immunosuppressive agents and related outcomes in organ transplantation patients in Taiwan. The main question it aims to answer is the risk of different immunosuppressive agents for infection and survival after transplant. The study enrolled patients who underwent solid organ transplant (SOT), kidney (ICD-9-CM code V42.0), liver (ICD-9-CM code V42.7), or lung (ICD-9-CM code V42.6) transplants. We employed propensity score matching (PSM) to establish a matched cohort. The study will compare SOT patients and general patients to explore the risk of different immunosuppressive agents for infection and survival.
This is a prospective observational study of MIPD in clinical practice for paediatric kidney transplant patients using tacrolimus and mycophenolic acid in Radboudumc. Dose individualization in paediatric kidney transplant patients using the InsightRX platform is performed as standard care, meaning that a pharmacokinetic model and drug levels measured at t=0, t=1 and t=2 hours will be used to calculate the exposure. Based on the estimated exposure, the pharmacist gives a dose recommendation to the physician, who can then modify the dosage of mycophenolic acid or tacrolimus. The selected dose and the measured MPA and tacrolimus concentrations will be used to predict the future exposure. A second exposure measurement will be performed to evaluate whether our model is able to predict future exposure.
1. Construct a population pharmacokinetic/pharmacodynamic model of tacrolimus in kidney transplant patients, and explore the quantitative relationship between combination drugs and gene polymorphisms on the safety and efficacy of tacrolimus in kidney transplant patients; 2. Based on the established pharmacokinetic/pharmacodynamic model of tacrolimus population in kidney transplant patients, combined with combined drugs, gene polymorphisms and other factors for simulation, predict the steady-state trough concentration and efficacy of tacrolimus in kidney transplant patients taking triple drugs (tacrolimus, mycophenolate mofetil/mycophenol sodium enteric-coated tablets, glucocorticoids), and apply the model to the real world to explore the optimal initial dose and maintenance therapeutic dose of tacrolimus, so as to achieve individualized and precise treatment and guide the rational clinical use of drugs. 3. Clarify the value of precision medicine guided by population pharmacokinetics/pharmacodynamics models in clinical practice.
This study is an analytical observational retrospective cohort study. It is a single-center study conducted in the Nancy University Hospital. End stage renal disease is the ultimate stage of the chronic kidney disease. Patients need extra-renal replacement techniques. Kidney transplantation is the most effective option for survival, quality of life and costs. Then long-term immunosuppressive agents are required to prevent allograft rejection and improve graft survival. The number of patients who return in dialysis after graft loss is increasing and accounts for 10% of incident dialysis patients and 14% of patients on the kidney transplant waiting list registered in 2019. This population may develop complications induced by end-stage renal disease and adverse events related to prolonged exposure to immunosuppressive agents. There are currently no formal guidelines on the management of immunosuppressive agents when patients return to dialysis. Reduction or discontinuation of therapy appears to decrease cardiovascular, infectious, and neoplastic complications. However, continuing these treatments may limit anti-HLA sensitization which may access to retransplantation. Only a few low-powered cohort studies have evaluated the impact of the management of immunosuppressive therapy on the HLA-sensitization. The hypothesis of our study is that the continuation of immunosuppressive agents when patients return in dialysis may limit anti-HLA sensitization. Therefore, access to retransplantation could be facilitated. The main objective is to compare the evolution of anti-HLA sensitization according to the management of immunosuppressive treatment after the return in dialysis (maintenance, reduction, cessation). Secondary objectives are time to re-transplantation for patients on the transplant waiting list, survival of the new graft, patient survival, and dialysis complications (cardiovascular, infectious and neoplastic complications).
This study will find the maximum safe dose (MSD) or maximum tolerated dose (MTD) of CYNK-001 which are NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy for the systemic cohort (IV) (intravenous). The intratumoral cohort (IT) will not be giving lymphodepletion. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating recurrent glioblastoma multiforme.
This study will find the maximum tolerated dose or the maximum planned dose of CYNK-001 which contains natural killer (NK) cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating acute myeloid leukemia.
Pneumocystis jiroveci pneumonia (PcP) increased in non HIV immunocompromised patients. Mortality remains high for those patients with comorbidities (50% for patients with the most severe Pneumocystis pneumonia). Physiopathology, characteristics and outcome of PcP in non-HIV patients remains different from those in HIV patients. Steroids in HIV patients with PcP has been associated with decreased mortality but in non-HIV patients, adjunctive steroids remains controversy. Some retrospective studies in that field did not find any beneficial effects of steroids ((1mg/kg/jour d'Equivalent Prednisone (EP)). However, all the studies were retrospective, non randomised studies including various underlying disease and severity of PcP was variable. Moreover, dosage and delay of steroids were variable leading difficult to interpret all the results. The investigators want to demonstrate the beneficial effect of steroid during PcP in non-HiV immunocompromised patients with a double blinded randomised clinical trials comparing adjunctive steroids to placebo.
An open, single center, randomised study to investigate three different immunosuppressive regimens for de novo renal transplant recipients: 1. st sirolimus / EC-MPS / tacrolimus regimen - After 3 months a protocol biopsy is performed. If no rejection is detected the calcineurin inhibitor (tacrolimus) is withdrawn. 2. nd everolimus / EC-MPS / tacrolimus regimen - After 3 months a protocol biopsy is performed. If no rejection is detected the calcineurin inhibitor (tacrolimus) is withdrawn. 3. rd tacrolimus / EC-MPS / prednisone regimen - After 3 months a protocol biopsy is performed. If no rejection is detected prednisone is withdrawn.
